After grisly discovery Saturday in the 2800 block of Fannin Street, police began searching for a missing black 2014 Nissan Maxima and Moseley's son. Police Detective Shawn Spruill declined to say who owned the Nissan. It was "a car that they had that he had access to," Spruill said.

Police found the teenager with the car Sunday in Houston, although police won't say where or whether he was alone. After questioning, police charged the boy with murder, saying that they believe he acted alone.

Authorities are withholding information about the manner of Moseley's death pending an autopsy to be completed Tuesday. Spruill said police were reluctant to disclose details because of the complexity of the investigation. "There are a lot of moving parts to this investigation," he said.

Kevin Petroff, Galveston County first assistant district attorney, said the boy would be detained for 10 days but offered no other information about the crime.

The body was discovered by a neighbor, who says he initially thought nothing of it when he found the door ajar to her home. Later, the neighbor, who asked not to be identified, worried that it had been burglarized. He said he then pushed the door open and found Moseley's body on the kitchen floor in a pool of dried blood.

The neighbor said Moseley and her son moved to La Marque in August.

"She was a good person," he said. "She was a great mother and really kind-hearted."

He said the mother and son seemed to stay home, with few visitors. "There wasn't a lot of drama," he said.

He said he chatted a few times with the teen, even tossing a football with him. "He seemed like a smart kid and a normal teenager."

Court documents reveal that Moseley had led a stormy life. She had been living on her own for a year in 1999 when at age 17 she sought emancipation so she could get an apartment, buy a car and get a GED, or high school equivalency diploma, court records show.

The next year she became embroiled in a legal dispute over the paternity and custody of a son. At one point Child Protective Services took custody of the boy, and Moseley was accused of having "a history or pattern of child neglect," according to court records.

Moseley and the father were ordered to pay child support and share custody with two others, whose relationship to the child was unclear in the court documents.

A spokeswoman for Child Protective Services declined to offer information about the child's history.

As her custody case dragged on, Moseley ran afoul of the law on several occasions.

She was accused of assault on a family member in 2004, although charges were dropped. She was accused of theft of less than $500 in 2005 and made restitution.

She was also accused of falsely reporting to police in 2009 that her boyfriend struck her and had pornography on his computer, court records show.

In 2010 Moseley was charged with assault on a man identified as her husband, who later obtained a restraining order barring her from contacting him. That same year she was arrested on a drunken driving charge; she received probation and had to pay a fine. In 2013 she was charged with failing to stop and give information following a traffic accident. She pleaded no contest.

Between 2001 and 2015, a court ordered her to forfeit her bond at least five times for failure to appear in court.

Moseley also struggled financially. Records show that she was sued twice for failing to pay her rent.

Records show that she ran Nita Maid Service from 2005 to 2007, but there is no record of the business after 2007.
